The bar added a message to other local businesses warning them of Zelaznog's unwelcome alleged practice.

Chris Kahn, co-owner of the Brewer's Cabinet explained to the Reno Gazette-Journal: "All his friends paid and left and he was the last one. The server needed to collect his money. He said he forgot his wallet."

The photo the server obtained was quite some close-up. And though Zelaznog told the Gazette-Journal that he would repay, he has now been arrested and jailed.

It seems that he was on probation. It also seems that other establishments were accusing him of similar dining-and-dashing daring.

The hospitality industry has been very much in the news lately for its use of social media to shame those whom it perceives as behaving badly.

Just as sites like Facebook and Yelp have allowed customers to bleat about poor food service and digestion, so bar and restaurant owners have discovered that they, too, can use social media to air their own grievances about customers and life in general.

This can backfire, as the now infamous Amy's Baking Company in Arizona discovered.

After a difficult appearance on "Ramsey's Kitchen Nightmares," the owners leaped to the restaurant's Facebook page to call out critics: "You people are all s***. Yelp s***, Reddits s***. Every s***. Come to here, I will f***ing show you all."
